Question

Q2. (a) Give a balanced chemical equation for the following conversions: Pb304 (i) → Pbo → Pb(NO3)2 Pb(OH)2 (iv) NazPbO2.Pls no span ,answer correctly and fast ,do not answer if u do not know!​

Answer 1

Explanation:

1. 2Pb₃O₄ → 6PbO + O₂

• 2 moles of Pb₃O₄ decomposed and give 6 moles of lead oxide.

2. Pb₃O₄ + 4HNO₃ → 2Pb(NO₃)₂ + PbO₂ + 2H₂O

• Pb₃O₄ react with 4 moles of nitric acid and give 2 moles of Lead nitrate, one mole of lead oxide and, 2 moles of water molecules.

3. 2Pb₃O₄ + 12NaOH → 6Pb(OH)₂ + 6Na₂O + O₂

• 2 moles of Pb₃O₄ react with 12 moles of sodium hydroxide and give 6 moles of Pb(OH)₂ and 6 moels of sodium oxide.

4. Pb₃O₄ + 6NaOH → 2Na₂PbO₂ + Na₂PbO₃ + 3H₂O

• Pb₃O₄ reacts with 6 moles of sodium hydroxide to give 2Na₂PbO₂, Na₂PbO₃, and 3H₂O
